On my recently purchased property I have a huge poison ivy problem.
Poison ivy is found in every rock wall (several), around the base of
nearly every tree (plenty), and even in large areas of grass (which
used to be over grown with tall grass and small shrubs). What is the
best method to kill the poison ivy without killing all the grass,
trees, and shrubs which surround it?

I have found 2 solutions effective.

1) RoundUp -- In areas where you cannot spray, use a paintbrush to apply it
directly to the leaves.

2) Urine -- Human or animal urine, directly on the leaves works wonders. My
dogs keep the fenceline clean now.
